The present invention relates to novel Δ¹-pyrrolines, to a plurality of processes for their preparation and to their use as pesticides.

It is already known that numerous Δ¹-pyrrolines have insecticidal properties (cf. WO 00/21958, WO 99/59968, WO 99/59967 and WO 98/22438). The activity of these substances is good; however, in some cases it is unsatisfactory.

This invention now provides novel Δ¹-pyrrolines of the formula (I)

in which

-   -   R¹ represents halogen or methyl,     -   R² represents hydrogen or halogen,     -   R³, R⁴, R⁵ and R⁶ independently of one another represent         hydrogen, halogen, C₁-C₄-alkyl or C₁-C₄-alkoxy,     -   X represents O (oxygen) or S (sulphur),     -   Y represents C¹⁰ or N (nitrogen),     -   R⁷, R⁸, R⁹ and R¹⁰ independently of one another represent         hydrogen, halogen, nitro, C₁-C₄-alkyl, C₁-C₄-haloalkyl,         C₁-C₄-haloalkoxy, C₁-C₄-haloalkylthio, C₁-C₄-alkoxycarbonyl,         phenyl, —(CH)_(m)—SO₂R¹¹ or —SO₂NR¹²R¹³, or either R⁷ and R⁸ or         R⁸ and R⁹ or R⁹ and R¹⁰ together form a further saturated or         unsaturated 5- or 6-membered ring which again may contain one or         two heteroatom groupings from the group consisting of N, O, S         and SO₂,     -   m represents 0 or 1,     -   R¹¹ represents C₁-C₄-alkyl or morpholino,     -   R¹² represents C₁-C₄-alkyl or represents phenyl which is         optionally mono- to tetrasubstituted by identical or different         substituents from the group consisting of halogen, C₁-C₄-alkyl         and C₁-C₄-alkoxy,     -   R¹³ represents hydrogen or C₁-C₄-alkyl.

Depending on the type and number of substituents, the compounds of the formula (I) may be present as geometrical and/or optical isomers or regioisomers or as mixtures of these isomers in varying composition. What is claimed by the invention are both the pure isomers and the isomer mixtures.

Furthermore, it has been found that the Δ¹-pyrrolines of the formula (I) can be prepared by

-   -   A) reacting compounds of the formula (II)         in which     -   R¹, R², R³, R⁴, R⁵, R⁶, X, Y, R⁷, R⁸ and R⁹ are as defined         above, with p-toluenesulphonic acid, if appropriate in the         presence of a diluent.

The formula (III) provides a general definition of the Δ¹-pyrrolines required as starting materials, for carrying out the process (a) according to the invention. In this formula, R¹, R², R³, R⁴, R⁵ and R⁶ preferably, particularly preferably and very particularly preferably have those meanings which have already been mentioned in connection with the description of the compounds of the formula (I) according to the invention as being preferred, particularly preferred, etc., for these radicals.

Δ¹-Pyrrolines of the formula (V) are known and/or can be prepared by known processes (cf. WO 98/22438 and DE10047109.9).

The formula (V) provides a general definition of the Δ¹-pyrrolines required as starting materials for carrying out the process (b) according to the invention. In this formula, R¹, R², R³, R⁴, R⁵ and R⁶ preferably, particularly preferably and very particularly preferably have those meanings which have already been mentioned in connection with the description of the compounds of the formula (I) according to the invention as being preferred, particularly preferred, etc., for these radicals.

Δ¹-Pyrrolines of the formula (V) are known and/or can be prepared by known processes (cf. WO 98/22438 and DE10047109.9).

Δ¹-Pyrrolines of the formula (V) can also be prepared by

-   -   c) reacting Δ¹-pyrrolines of the formula (III)         in which     -   R¹, R², R³, R⁴, R⁵ and R⁶ are as defined above,     -   in a first step with an alcohol of the formula (VI)         R¹⁴—OH   (VI)         in which     -   R¹⁴ represents C₂-C₆-alkyl, preferably C₂-C₄-alkyl, particularly         preferably ethyl or n-butyl, very particularly preferably         n-butyl,     -   in the presence of carbon monoxide, in the presence of a base         (for example diisopropylethylamine) and in the presence of a         catalyst (for example PdCl₂/PPh₃/dppp)     -   and, in a second step, hydrolyzing the resulting Δ¹-pyrrolines         of the formula (VII)         in which     -   R¹⁴ is as defined above     -   in the presence of an acid (for example 20% strength HCl) and,         if appropriate,     -   in the presence of a diluent (for example ethylene glycol         dimethyl ether).

The formula (IV) provides a general definition of the aniline derivatives required as starting materials for carrying out the processes (a) and (b) according to the invention.

Aniline derivatives of the formula (IV) are known and/or can be prepared by known processes.

Aniline derivatives of the formula (IV) can be prepared, for example, from the analogous nitroaryl compounds (cf. WO 99/32436). The reduction of the nitro group to the amine is carried out either by using a metal catalyst (for example Ni, Pd, Pt) in the presence of hydrogen or a hydride donor (for example formate, cyclohexadiene, borohydride) (cf. Rylander: Hydrogenation Methods; Academic Press, London 1985). Nitroaryls can also be reduced directly by employing a strong hydride source (for example LiAnH₄, cf. Seyden-Penne: Reductions by the Alumino- and Borohydrides in Organic Synthesis; VCH Publishers, New York 1991) or by using a zerovalent metal (for example Fe, Sn, Ca), if appropriate in the presence of an acid. The nitroaryl compounds are obtained by known processes (cf. March: Advanced Organic Chemistry, 3^(rd) Ed., John Wiley, New York 1985).

The Δ¹-pyrrolines of the formula (III) required as starting materials for carrying out the process (c) according to the invention have already been described above.

The alcohols of the formula (VI) required as starting materials for carrying out the process (c) according to the invention are known.

Suitable diluents for carrying out the process (A) according to the invention are all customary inert organic solvents. Preference is given to using optionally halogenated aliphatic, alicyclic or aromatic hydrocarbons, such as petroleum ether, hexane, heptane, cyclohexane, methylcyclohexane, benzene, toluene, xylene or decalin; chlorobenzene, dichlorobenzene, dichloromethane, chloroform, carbon tetrachloride, dichloroethane or trichloroethane; ethers, such as diethyl ether, diisopropyl ether, methyl tert-butyl ether, methyl tert-amyl ether, dioxane, tetrahydrofuran, 1,2-dimethoxyethane, 1,2-diethoxyethane or anisole; nitriles, such as acetonitrile, propionitrile, n- or isobutyronitrile or benzonitrile; amides, such as N,N-dimethylformamide, N,N-dimethylacetamide, N-methylformanilide, N-methylpyrrolidone or hexamethylphosphoric triamide; esters, such as methyl acetate or ethyl acetate; sulphoxides, such as dimethyl sulphoxide; or sulphones, such as sulpholane. Particular preference is given to using acetone, dimethoxyethane, dioxane, tetrahydrofuran, dimethylformamide, dimethylacetamide, dimethyl sulphoxide, ethanol, toluene or, if appropriate, mixtures of the diluents mentioned with water. Particular preference is given to using toluene or benzene.

When carrying out the process (A) according to the invention, the reaction temperatures can be varied within a relatively wide range. In general, the process is carried out at temperatures between 0° C. and 140° C., preferably between 20° C. and 120° C., particularly preferably between 80° C. and 120° C.

All of the processes according to the invention are generally carried out under atmospheric pressure. However, in each case it is also possible to operate under elevated or reduced pressure.

When carrying out the process (A) according to the invention, in general from 2 to 4 mol of p-toluenesulphonic acid are employed per mole of the compound of the formula (II). However, it is also possible to employ the reaction components in other ratios. Work-up is carried out by customary methods. In general, the reaction mixture is diluted and extracted with an organic solvent. The organic phase is washed, dried, filtered and concentrated. If appropriate, the residue is freed of any impurities that may still be present using customary methods, such as chromatography or recrystallization.

Chiral Compounds of the Formula (I-a)

To produce chiral compounds of the formula (I-a), it is possible, for example, to subject the Δ¹-pyrrolines, used as intermediates, of the formula (III)

in which

-   -   R¹, R², R³, R⁴, R⁵ and R⁶ are as defined above,     -   to an optical resolution. This is effected, for example, using         methods of preparative chromatography, preferably the High         Performance Liquid Chromatography (HPLC) method. For this         purpose, a chiral stationary silica gel phase is used. A         tris-(3,5-dimethylphenylcarbamate) cellulose-modified silica gel         has been found to be particularly suitable for separating the         compounds of the formula (III) into the two enantiomers. This         separation material is commercially available. However, it is         also possible to use other stationary phases. Suitable eluents         are all customary inert organic solvents, and mixtures of these.         Preference is given to using optionally halogenated aliphatic,         alicyclic or aromatic hydrocarbons, such as petroleum ether,         hexane, heptane, cyclohexane; dichloromethane, chloroform;         alcohols, such as methanol, ethanol, propanol; nitriles, such as         acetonitrile; esters, such as methyl acetate or ethyl acetate.         Particular preference is given to using aliphatic hydrocarbons,         such as hexane or heptane, and alcohols, such as methanol or         propanol, very particularly preferably n-heptane and         isopropanol, or mixtures of these. In general, this is effected         at temperatures between 10° C. and 60° C., preferably between         10° C. and 40° C., particularly preferably at room temperature.         The (R)-configured enantiomers obtained in this manner are then         used as starting materials for process (a) or (c).

The active compounds, having good plant tolerance, favourable homeotherm toxicity and good environmental compatibility, are suitable for protecting plants and plant organs, for increasing harvest yields, for improving the quality of the harvested produce and for controlling animal pests, in particular insects, arachnids and nematodes, which are encountered in agriculture, in forests, in gardens and leisure facilities, in the protection of stored products and of materials, and in the hygiene sector.

These formulations are produced in a known manner, for example by mixing the active compounds with extenders, that is liquid solvents and/or solid carriers, optionally with the use of surfactants, that is emulsifiers and/or dispersants, and/or foam-formers.

If the extender used is water, it is also possible to employ for example organic solvents as auxiliary solvents. Essentially, suitable liquid solvents are: aromatics such as xylene, toluene or alkylnaphthalenes, chlorinated aromatics or chlorinated aliphatic hydrocarbons such as chlorobenzenes, chloroethylenes or methylene chloride, aliphatic hydrocarbons such as cyclohexane or paraffins, for example petroleum fractions, mineral and vegetable oils, alcohols such as butanol or glycol and also their ethers and esters, ketones such as acetone, methyl ethyl ketone, methyl isobutyl ketone or cyclohexanone, strongly polar solvents such as dimethylformamide and dimethyl sulphoxide, and also water.

Suitable solid carriers are:

-   -   for example ammonium salts and ground natural minerals such as         kaolins, clays, talc, chalk, quartz, attapulgite,         montmorillonite or diatomaceous earth, and ground synthetic         minerals, such as finely divided silica, alumina and silicates;         suitable solid carriers for granules are: for example crushed         and fractionated natural rocks such as calcite, marble, pumice,         sepiolite and dolomite, and also synthetic granules of inorganic         and organic mieals, and granules of organic material such as         sawdust, coconut shells, maize cobs and tobacco stalks; suitable         emulsifiers and/or foam-formers are: for example nonionic and         anionic emulsifiers, such as polyoxyethylene fatty acid esters,         polyoxyethylene, fatty alcohol ethers, for example alkylaryl         polyglycol ethers, alkylsulphonates, alkyl sulphates,         arylsulphonates and also protein hydrolysates; suitable         dispersants are: for example lignosulphite waste liquors and         methylcellulose.

Tackifiers such as carboxymethylcellulose and natural and synthetic polymers in the form of powders, granules or latices, such as gum arabic, polyvinyl alcohol and polyvinyl acetate, as well as natural phospholipids such as cephalins and lecithins, and synthetic phospholipids, can be used in the formulations. Other additives can be mineral and vegetable oils.

It is possible to use colorants such as inorganic pigments, for example iron oxide, titanium oxide and Prussian Blue, and organic dyes, such as alizarin dyes, azo dyes and metal phthalocyanine dyes, and trace nutrients such as salts of iron, manganese, boron, copper, cobalt, molybdenum and zinc.

The formulations generally comprise between 0.1 and 95% by weight of active compound, preferably between 0.5 and 90%.

The active compounds according to the invention can be used as such or in their formulations as a mixture with known fungicides, bactericides, acaricides, nematicides or insecticides in order to extend the spectrum of activity or prevent resistances developing. In many cases, synergistic effects are thus obtained, ie. the efficacy of the mixture is greater than the efficacy of the individual components.

A mixture with other known active compounds, such as herbicides, or with fertilizers and growth regulators, safeners or semiochemicals is also possible.

The active compounds according to the invention, can furthermore be present when used as insecticides in their commercially available formulations and in the use forms, prepared from these formulations, as a mixture with synergistic agents. Synergistic agents are compounds which increase the effect of the active compounds, without the added synergistic agent itself having to be actively effective.

The active compounds according to the invention can furthermore be present when used as insecticides in their commercially available formulations and in the use forms, prepared from these formulations, as a mixture with inhibitors which reduce degradation of the active compound after use in the vicinity of the plant, on the surface of parts of plants or in plant tissues.

The active compound content of the use forms prepared from the commercially available formulations can vary within wide limits. The active compound concentration of the use forms can be from 0.0000001 to 95% by weight of active compound, preferably between 0.0001 and 1% by weight.

The compounds are employed in a customary manner appropriate for the use forms.

When used against hygiene pests and pests of stored products, the active compound is distinguished by an excellent residual action on wood and clay as well as a good stability to alkali on limed substrates.

As already mentioned above, it is possible to treat all plants and their parts according to the invention. In a preferred embodiment, wild plant species and plant cultivars, or those obtained by conventional biological breeding, such as crossing or protoplast fusion, and parts thereof, are treated. In a further preferred embodiment, transgenic plants and plant cultivars obtained by genetic engineering, if appropriate in combination with conventional methods (Genetically Modified Organisms), and parts thereof are treated. The term “parts” or “parts of plants” or “plant part's” has been explained above.

Particularly preferably, plants of the plant cultivars which are in each case commercially available or ink use are treated according to the invention. Plant cultivars are to be understood as meaning plants, having novel properties (“traits”) which have been obtained by conventional breeding, by mutagenesis or by recombinant DNA techniques. This can be varieties, bio- and genotypes.

Depending on the plant species or plant cultivars, their location and growth conditions (soils, climate, vegetation period, diet), the treatment according to the invention may also result in superadditive (“synergistic”) effects. Thus, for example, reduced application rates and/or a widening of the activity spectrum and/or an increase in the activity of the substances and compositions to be used according to the invention, better plant growth, increased tolerance to high or low temperatures, increased tolerance to drought or to water or soil salt content, increased flowering performance, easier harvesting, accelerated maturation, higher harvest yields, better quality and/or a higher nutritional value of the harvested products, better storage stability and/or processability of the harvested products are possible which exceed the effects which were actually to be expected.

The transgenic plants or plant cultivars to be treated (i.e. those obtained by genetic engineering) which are preferred according to the invention include all plants which, in the genetic modification, received genetic material which imparted particularly advantageous useful traits to these plants. Examples of such traits are better plant growth, increased tolerance to high or low temperatures, increased tolerance to drought or to water or soil salt content, increased flowering performance, easier harvesting, accelerated maturation, higher harvest yields, better quality and/or a higher nutritional value of the harvested products, better storage stability and/or processability of the harvested products. Further and particularly emphasized examples of such traits are a better defence of the plants against animal and microbial pests, such as against insects, mites, phytopathogenic fungi, bacteria and/or viruses, and also increased tolerance of the plants to certain herbicidally active compounds. Examples of transgenic plants which may be mentioned are the important crop plants, such as cereals (wheat, rice), maize, soya beans, potatoes, cotton, tobacco, oilseed rape and also fruit plants (with the fruits apples, pears, citrus fruits and grapevines), and particular emphasis is given to maize, soya beans, potatoes, cotton, tobacco and oilseed rape. Traits that are emphasized are in particular increased defence of the plants against insects, arachnids, nematodes and snails by toxins formed in the plants, in particular those formed by the genetic material from Bacillus thuringiensis (for example by the genes CryIA(a), CryIA(b), CryIA(c), CryIIA, CryIIIA, CryIIIB2, Cry9c, Cry2Ab, Cry3Bb and CryIF and also combinations thereof) in the plants (hereinbelow referred to as “Bt plants”). Traits that are also particularly emphasized are the increased defence of the plants to fungi, bacteria and viruses by systemic acquired resistance (SAR), systemin, phytoalexius, elicitous and resistance genes and correspondingly expressed proteins and toxins. Traits that are furthermore particularly emphasized are the increased tolerance of the plants to certain herbicidally active compounds, for example imidazolinones, sulphonylureas, glyphosate or phosphinotricin (for example the “PAT” gene). The genes which impart the desired traits in question can also be present in combination with one another in the transgenic plants. Examples of “Bt plants” which may be mentioned are maize varieties, cotton varieties, soya bean varieties and potato varieties which are sold under the trade names YIELD GARD® (for example maize, cotton, soya beans), KnockOut® (for example maize), StarLink® (for example maize), Boligard® (cotton), Nucotn® (cotton) and NewLeaf® (potato). Examples of herbicide-tolerant plants which may be mentioned are maize varieties, cotton varieties and soya bean varieties which are sold under the trade names Roundup Ready® (tolerance to glyphosate, for example maize, cotton, soya bean), Liberty Link® (tolerance to phosphinotricin, for example oilseed rape), IMI® (tolerance to imidazolinones) and STS® (tolerance to sulphonylureas, for example maize). Herbicide-resistant plants (plants bred in a conventional manner for herbicide tolerance) which may be mentioned include the varieties sold under the name Clearfield® (for example maize). Of course, these statements also apply to plant cultivars having these or still-to-be-developed genetic traits, which plants will be developed and/of marketed in the future.

The plants listed can be treated according to the invention in a particularly advantageous manner with the compounds of the general formula (I) or the active compound mixtures according to the invention. The preferred ranges stated above for the active compounds or mixtures also apply to the treatment of these plants. Particular emphasis is given to the treatment of plants with the compounds or the mixtures specifically mentioned in the present text.

The active compounds according to the invention act not only against plant, hygiene and stored product pests, but also in the veterinary medicine sector against animal parasites (ectoparasites), such as hard ticks, soft ticks, mange mites, leaf mites, flies (biting and licking), parasitic fly larvae, lice,. hair lice, feather lice and fleas. These parasites include:

From the order of the Anoplurida, for example, Haematopinus spp., Linognathus spp., Pediculus spp., Phtirus spp. and Solenopotes spp.

From the order of the Mallophagida and the suborders Amblycerina and Ischnocerina, for example, Trimenopon spp., Menopon spp., Trinoton spp., Bovicola spp., Werneckiella spp., Lepikentron spp., Damalina spp., Trichodectes spp. and Felicola spp.

From the order Diptera and the suborders Nematocerina and Brachycerina, for example, Aedes spp., Anopheles spp., Culex spp., Simulium spp., Eusimulium spp., Phlebotomus spp., Lutzomyia spp., Culicoides spp., Chrysops spp., Hybomitra spp., Atylotus spp., Tabanus spp., Haematopota spp., Philipomyia spp., Braula spp., Musca spp., Hydrotaea spp., Stomoxys spp., Haematobia spp., Morellia spp., Fannia spp., Glossina spp., Calliphora spp., Lucilia spp., Chrysomyia spp., Wohlfahrtia spp., Sarcophaga spp., Oestrus spp., Hypoderma spp., Gasterophilus spp., Hippobosca spp., Lipoptena spp. and Melophagus spp.

From the order of the Heteropterida, for example, Cimex spp., Triatoma spp., Rhodnius spp. and Panstrongylus spp.

From the order of the Blattarida, for example, Blatta orientalis, Periplaneta americana, Blattela germanica and Supella spp.

From the subclass of the Acaria (Acarida) and the orders of the Meta- and Mesostigmata, for example, Argas spp., Omithodorus spp., Otobius spp., Ixodes spp., Amblyomma spp., Boophilus spp., Dermacentor spp., Haemophysalis spp., Hyalomma spp., Rhipicephalus spp., Dermanyssus spp., Raillietia spp., Pneumonyssus spp., Sternostoma spp. and Varroa spp.

From the order of the Actinedida (Prostigmata) and Acaridida (Astigmata), for example, Acarapis spp., Cheyletiella spp., Ornithocheyletia spp., Myobia spp., Psorergates spp., Demodex spp., Trombicula spp., Listrophorus spp., Acarus spp., Tyrophagus spp., Caloglyphus spp., Hypodectes spp., Pterolichus spp., Psoroptes spp., Chorioptes spp., Otodectes spp., Sarcoptes spp., Notoedres spp., Knemidocoptes spp., Cytodites spp. and Laminosioptes spp.

The active compounds of the formula (I) according to the invention are also suitable for controlling arthropods which infest agricultural productive livestock, such as, for example, cattle, sheep, goats, horses, pigs, donkeys, camels, buffalo, rabbits, chickens, turkeys, ducks, geese and bees, other pets, such as, for example, dogs, cats, caged birds and aquarium fish, and also so-called test animals, such as, for example, hamsters, guinea pigs, rats and mice. By controlling these arthropods, cases of death and reduction in productivity (for meat, milk, wool, hides, eggs, honey etc.) should be diminished, so that more economic and easier animal husbandry is possible by use of the active compounds according to the invention.

The active compounds according to the invention are used in the veterinary sector in a known manner by enteral administration in the form of, for example, tablets, capsules, potions, drenches, granules, pastes, boluses, the feed-through process and suppositories, by parenteral administration, such as, for example, by injections (intramuscular, subcutaneous, intravenous, intraperitoneal and the like), implants, by nasal administration, by dermal use in the form, for example, of dipping or bathing, spraying, pouring on and spotting on, washing and powdering, and also with the aid of moulded articles containing the active compound, such as collars, ear marks, tail marks, limb bands, halters, marking devices and the like.

When used for cattle, poultry, pets and the like, the active compounds of the formula (I) according to the invention can be used as formulations (for example powders, emulsions, free-flowing compositions), which comprise the active compounds according to the invention in an amount of 1 to 80% by weight, directly or after 100 to 10 000-fold dilution, or they can be used as a chemical bath.

Bristletails, such as Lepisma saccharina.

Industrial materials in the present context are to be understood as meaning non-living materials, such as, preferably, plastics, adhesives, sizes, papers and cards, leather, wood and processed wood products and coating compositions.

Wood and processed wood products are materials to be protected, especially preferably, from insect infestation.

Wood and processed wood products which can be protected by the agent according to the invention or mixtures comprising this are to be understood as meaning, for example:

-   -   building timber, wooden beams, railway sleepers, bridge         components, boat jetties, wooden vehicles, boxes, pallets,         containers, telegraph poles, wood panelling, wooden windows and         doors, plywood, chipboard, joinery or wooden products which are         used quite generally in house-building or in building joinery.

The active compounds can be used as such, in the form of concentrates or in generally customary formulations, such as powders, granules, solutions, suspensions, emulsions or pastes.

The formulations mentioned can be prepared in a manner known per se, for example by mixing the active compounds with at least one solvent or diluent, emulsifier, dispersing agent and/or binder or fixing agent, a water repellent, if appropriate siccatives and UV stabilizers and if appropriate dyes and pigments, and also other processing auxiliaries.

The insecticidal compositions or concentrates used for the preservation of wood and wood-derived timber products comprise the active compound according to the invention in a concentration of 0.0001 to 95% by weight, in particular 0.001 to 60% by weight.

The amount of the compositions or concentrates employed depends on the nature and occurrence of the insects and on the medium. The optimum amount employed can be determined for the use in each case by a series of tests. In general, however, it is sufficient to employ 0.0001 to 20% by weight, preferably 0.001 to 10% by weight, of the active compound, based on the material to be preserved.

Solvents and/or diluents which are used are an organic chemical solvent or solvent mixture and/or an oily or oil-like organic chemical solvent or solvent mixture of low volatility and/or a polar organic chemical solvent or solvent mixture and/or water, and if appropriate an emulsifier and/or wetting agent.

Organic chemical solvents which are preferably used are oily or oil-like solvents having an evaporation number above 35 and a flashpoint above 30° C., preferably above 45° C. Substances which are used as such oily or oil-like water-insoluble solvents of low volatility are appropriate mineral oils or aromatic fractions thereof, or solvent mixtures containing mineral oils, preferably white spirit, petroleum and/or alkylbenzene.

Mineral oils having a boiling range from 170 to 220° C., white spirit having a boiling range from 170 to 220° C., spindle oil having a boiling range from 250 to 350° C., petroleum and aromatics having a boiling range from 160 to 280° C., turpentine oil and the like, are advantageously employed.

In a preferred embodiment, liquid aliphatic hydrocarbons having a boiling range from 180 to 210° C. or high-boiling mixtures of aromatic and aliphatic hydrocarbons having a boiling range from 180 to 220° C. and/or spindle oil and/or monochloronaphthalene, preferably α-monochloronaphthalene, are used.

The organic oily or oil-like solvents of low volatility which have an evaporation number above 35 and a flashpoint above 30° C., preferably above 45° C., can be replaced in part by organic chemical solvents of high or medium volatility, providing that the solvent mixture likewise has an evaporation number above 35 and a flashpoint above 30° C., preferably above 45° C., and that the insecticide/fungicide mixture is soluble or emulsifiable in this solvent mixture.

According to a preferred embodiment, some of the organic chemical solvent or solvent mixture is replaced by an aliphatic polar organic chemical solvent or solvent mixture. Aliphatic organic chemical solvents containing hydroxyl and/or ester and/or ether groups, such as, for example, glycol ethers, esters or the like, are preferably used.

Organic chemical binders which are used in the context of the present invention are the synthetic resins and/or binding drying oils which are known per se, are water-dilutable and/or are soluble or dispersible or emulsifiable in the organic chemical solvents employed, in particular binders consisting of or comprising an acrylate resin, a vinyl resin, for example polyvinyl acetate, polyester resin, polycondensation or polyaddition resin, polyurethane resin, alkyd resin or modified alkyd resin, phenolic resin, hydrocarbon resin, such as indene-cumarone resin, silicone resin, drying vegetable oils and/or drying oils and/or physically drying binders based on a natural and/or synthetic resin.

The synthetic resin used as the binder can be employed in the form of an emulsion, dispersion or solution. Bitumen or bituminous substances can also be used as binders in an amount of up to 10% by weight. Dyestuffs, pigments, water-repelling agents, odour correctants and inhibitors or anticorrosive agents and the like which are known per se can additionally be employed.

It is preferred according to the invention for the composition or concentrate to comprise, as the organic chemical binder, at least one alkyd resin or modified alkyd resin and/or one drying vegetable oil. Alkyd resins having an oil content of more than 45% by weight, preferably 50 to 68% by weight, are preferably used according to the invention.

All or some of the binder mentioned can be replaced by a fixing agent (mixture) or a plasticizer (mixture). These additives are intended to prevent evaporation of the active compounds and crystallization or precipitation. They preferably replace 0.01 to 30% of the binder (based on 100% of the binder employed).

The plasticizers originate from the chemical classes of phthalic acid esters, such as dibutyl, dioctyl or benzyl butyl phthalate, phosphoric acid esters, such as tributyl phosphate, adipic acid esters, such as di-(2-ethylhexyl)adipate, stearates, such as butyl stearate or amyl stearate, oleates, such as butyl oleate, glycerol ethers or higher molecular weight glycol ethers, glycerol esters and p-toluenesulphonic acid esters.

Fixing agents are based chemically on polyvinyl alkyl ethers, such as, for example, polyvinyl methyl ether or ketones, such as benzophenone or ethylenebenzophenone. Possible solvents or diluents are, in particular, also water, if appropriate as a mixture with one or more of the abovementioned organic chemical solvents or diluents, emulsifiers and dispersing agents.

Particularly effective preservation of wood is achieved by impregnation processes on a large industrial scale, for example vacuum, double vacuum or pressure processes.

The ready-to-use compositions can also comprise other insecticides, if appropriate, and also one or more fungicides, if appropriate.

Possible additional mixing partners are, preferably, the insecticides and fungicides mentioned in WO 94/29 268. The compounds mentioned in this document are an explicit constituent of the present application.

Especially preferred mixing partners which may be mentioned are insecticides, such as chlorpyriphos, phoxim, silafluofin, alphamethrin, cyfluthrin, cypermethrin, deltamethrin, permethrin, imidacloprid, NI-25, flufenoxuron, hexaflumuron, transfluthrin, thiacloprid, methoxyphenoxide, triflumuron, clothianidin, spinosad, tefluthrin and triflumuron,

The compounds according to the invention can at the same time be employed for protecting objects which come into contact with salt water or brackish water, such as hulls, screens, nets, buildings, moorings and signalling systems, against fouling.

Fouling by sessile Oligochaeta, such as Serpulidae, and by shells and species from the ledamorpha group (goose barnacles), such as various Lepas and Scalpellum species, or by species from the Balanomorpha group (acorn barnacles), such as Balanus or Pollicipes species, increases the frictional drag of ships and, as a consequence, leads to a marked increase in operation costs owing to higher energy consumption and additionally frequent residence in the dry dock.

Apart from fouling by algae, for example Ectocarpus sp. and Cerarnium sp., fouling by sessile Entomostraka groups, which come under the generic term Cirripedia (cirriped crustaceans), is of particular importance.

Surprisingly, it has now been found that the compounds according to the invention, alone or in combination with other active compounds, have an outstanding antifouling action.

Furthermore, the paints may comprise plasticizers, modifiers which affect the theological properties and other conventional constituents. The compounds according to the invention or the abovementioned mixtures may also be incorporated into self-polishing antifouling systems.

The active compounds are also suitable for controlling animal pests, in particular insects, arachnids and mites, which are found in enclosed spaces such as, for example, dwellings, factory halls, offices, vehicle cabins and the like.
